LIQUID-FUEL BURNER.

To all whomit may concern:

Be it known, that I, EDWARD C. KAHN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Liquid- Fuel Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

Thi invention relates to new and useful vaporized liquid fuel.

The primary object of this invention is to improve upon the structures illustrated in applications, Serial Nos. 171,338 and" 189,511, filed respectively on May 28, 1917 I and. Sept. 4, 1917, by simplifying the various ment for directing heat onto the va elements whereby to render their assemblage.

easier and their cost of manufacturedess.

It is a more particular object of this invention to provide an improved vaporizing pipe in combination with a spray ngzzle which can be very readily disconnected rom theburner proper and cleaned of any accumulation of soot or the like.

A further object is to provide an orizing I pipe without disposing the latter directly over the burner.

An additional object is'to provide a simple arrangement for adjustably. attaching the combined vaporizing pipe and spray nozzle to the burner proper.

With the foregoing objects in view and taken substantially on the plane of the line,

application filed January 25, 1918. Serial No. 213,660.

Fig. 5 is a substantially on the plane of the line 5-5 ofFig. 2.

' Certain of the parts illustrated in the present application drawings are particularly described and claimed as well as shown in the'above mentioned co-pending applications, therefore the construction and operation of these parts willnot be gone into in this applicatlon.

By reference to the drawings it will be noted that the numeral -1 designates the nning or expansion chamber of my proved burner, said chamber being defined by an upper circular plate or wall 2 from which depends an'annular wall 3, and a circular bottom 4, to which any suitable support may be secured as at 5. The interior of the'expansion chamber is divided by parthe latter 'ofthe two applications mentioned above-.'- I

As is also the case in said co-pending ap plication the top wall. 2 is provided at its outer peripheral edge with an upwardly and outwardly-inclined flange 6 to form airecess in which is seated a' burner cap 7 providing with the said Walla burner head. The gas outlets between said cap and wall may be constructed as shown in either of said copending applications although they are, in the present invention, illustrated as in application Serial No. 189,5 11. I

Referring now to the more novel feature of the present case 8 denotes a curved vapordetail horizontal section taken particularly a tition walls and a baflie plate as shown in i zing pipe having one end portion reduced in cross sectional area as at9, said portion. being disposed substantially vertical when in normal position. From Fig. 4 it will. be seen that both ends of the vaporizing pipe are internallythreaded .to receive a reduced coupling 10 and a plug 11, the former being threaded in the large end, and the latter in.

the end of thereduced portion. These parts are obviously quickly and easily removable so that when necessary the vaporizing pipe may be thoroughly cleansed of any foreign matter which may have collected on its innenwall; The coupling 10 is designed to be connected with av pipe from any suitable source of-fuel supply.

From Fig. 1 it will be notedthat, the

vaporizing pipe 8 is curved only in one di- 30 is frictionally engaged with the flange 14 and an arm '16 rection, thus differentiating it from similar pipes shown in the co-pending applications above noted. In other words in plan view the pipe 8 appears to be straight and is not disposed over the burner and receives heat therefrom in a 'manner to be hereinafter more particularly described.

Said vaporizing pipe is held in adjusted positions with respect to the burnerby the engagement of a cylindrical stud 12 projecting from the portion 9 of said pipe with asocket 13 of a boss lt, the, latter being cast integrally with the tog 7 burner. For holding the-stud in the socket a reinforced flange 15 extends from the boss screw 17 that extends through an enlarged apertureor'slot18 in the arm 16 and into a threaded opening in of the stud within the socket to a slight degree for the purpose of adjusting either the reduced portion 9 of the pipe nozzle which is usually flame from the burner the vaporizing pipe vaporizing pipe with respect to the burner openings or the fuel discharge opening 19 with the mixing or expansion chamber inlet 20. When the proper adjustment has been made the screw 17 is tightened and a looking screw 21 threaded through the arm 16 as will readily appear from Fig. 5.

The fuel discharge opening 19 is in the 8 and alined therewith isthe threaded opening 22 in a sleeve 23 that is formed integrally with said pipe 8. A valve stem 24 is threaded through the sleeve 23 and carries a valve head 25 for opening and closing the discharge outlet 19. handle 26 is formed on the end of the stem 24 for readily manipulating the valve.

pipe 8 and connecting the ends caused by the interruption with a horizontal flange or wall 28, from the inner edge of which depends an apron 29. Fig. .1 shows this apron 29 disposed inwardly of that portion'of the burner openings adjacent the pipe 8 so that the flames from said openings which strike against said apron and the wall 28 will be deflected outwardly. Also forming a porit will be has beenproduced which is a considerable plate 2 of the from the portion of v the pipe 8, said flange'and arm being re-f .tained in cooperative relationship by a the flange 15. The en-' larged aperture or slot 18 permits rotation.

naeaiea tion of the flame deflecting means is an arcuate flange 30 which extends from one end of the wall 28 and is disposed partly around that portion of the vaporizing pipe which is adjacent the reduced end 9.

From the foregoing description taken-in connection with the accompanying drawings evident that a liquid fuel burner improvement over the similar burners illus-' trated in said co-pending applications. The

new features illustrated in the present application when combined with those claimed in the other applications will provide a most 'eflicient and economical burner.

Various changes may be made in the form and proportions aswell as other details of structure without departing from or sacrificing any of theprinciples as outlined in the appended claims.

ll claim 1. In a device of the class described, a'

one-piece combined vap'orlzing tube and discharge nozzle comprising a pipe. open at both ends and internally screw threaded ad jacent its opposite ends, one end portion being reduced in diameter, said reduced end portion having transversely extending alined openings, one of said openings forming a fuel discharge port, an outwardly extending internally opposite opening, a threaded valve stem disposed through said sleeve and having a valve head to control the discharge port, a closure p and a couplingscrewed' into the. opposite end of said pipe.
